Corner fastener for chairs



Sept. 8, 1953 w. c. LUCAS CORNER FASTENER FOR CHAIRS Filed June 12, 1950lung'- INVENTOR WALTER C. LUCAS BYZM'I 5 4% ATTORNEY Patented Sept. 8,1953 CORNER FASTENER FOR CHAIRS Walter C.,Lucas,'Asheboro, N. 0.Application June 12, 1950, Serial No. 167,525 2 Claims. (Cl. 155-196)This invention relates to chairs for general use and the particularobject of the invention is to provide a chair of sturdy and simpleconstruction.

An important feature of the invention resides in locating all of thelegs within the seat frame of the chair, and by extending the back legsupwardly, utilizing them as a support for the back of the chair.

An equally important feature of the invention is a chair constructionwherein the legs are braced against the corners of the seat frame andsecured to each adjacent side of the frame at the respective corners.

Another feature of the invention resides in supporting the seat by meansof the seat frame, the legs, and corner braces for the seat frame.

A feature which produces a strong and simply built seat frame resides injoining the ends of the seat frame at the corners by mitered joints andconnecting the mitered corner joints by an embedded fiat metal strip.Thereby is avoided the use of dowels, nails and similar devices formerlyemployed in chair manufacturing.

A further advantage of the invention resides in a chair havingrelatively few parts which may be easily assembled and, if necessary,easily repaired.

Referring to the drawings:

Figure 1 is a side view partly broken away;

Figure 2 is a front view;

Figure 3 is a rear view; and

Figure 4 is a, section on the line 4-4 of Figure 2 through the rear leg.

In Figure l the seat frame is indicated as a whole at I upon which ispositioned the seat I I, the seat being supported by the frame and thefront legs I2 and the rear legs I3.

The seat frame I2 consists of four pieces of wood, the ends of which areneatly connected as by a mitered joint I4 and are held together by theembedded fiat metal strip I5, as shown in Figure 4 which extends acrossthe joint, as shown. At each corner of the frame I0 there is provided abrace I6, which, it will be noted, extends interiorly of the seat frameand is connected to the adjacent two sides thereof by countersunk screwsI1. The seat is held in position in the usual manner by means of screwsIII which extend upwardly from the braces to engage the wooden base I9of the seat. This wooden base is covered with any suitable type ofupholstery 20 in the usual manner. Referring to Figure 1, it will benoted that the seat is supported by the front legs, as well as by theseat frame, and by the braces I6.

' Each leg fits neatly into a corner of-the chair, as shown in Figure 4,and is connected' to the adjacent side members of the seat frame III bymeans of the countersunk screws 2| and 22 which extend at right anglesto each other. Thus, the legs are braced against the sides of the seatframe at the respective corners, as shown at 23, and connected to theadjacent sides, so that a sturdy construction is provided. This rigidityand strength is further enhanced by the provision of corner blocks I6,as shown in Figure 4 which are glued or otherwise secured to theadjacent side of the seat frame and a leg at each corner of the chairseat frame.

At the back of the chair, the rear legs l3 are extended upwardly, asshown at I3, and to their spaced upper ends is connected, by screws 24or in any other suitable manner, the upholstered back of the chair 25.The seat II is cut away, as shown at 26 in Figures 1 and 3 justsufficient to allow the extended portions of the legs I3 to passtherethrough and form a neat appearing structure.

The rear legs adjacent the seat frame III are undercut to providerecesses, as at 21, on the two sides abutting the adjacent cornerportions of the sides of the seat frame, as shown in Figures 1, 3 and 4,so as to receive these sides of the seat frame and support the same, asshown at 28. Also, the front legs are undercut to form ledges 29 on oneside to support the opposite sides of the seat frame at the frontportion of the seat.

By arranging all of the legs so that they are disposed within the seatframe, in the manner described, a chair having substantial rigidity isproduced and, at the same time, a very comfortable and attractivearticle is obtained. In thi connection, and referring to Figure 4, itwill be noted that the brace I6 can be arranged so as to have one sideabut the adjacent corner of each leg, as shown at 30, which will impartadditional strength to the chair.

By cutting away the seat II at the rear corners, as shown at 26, it ispossible to utilize the legs I3 by reason of their integral extensionsI3 to form the support for the back which will result in considerablesaving of both labor and material, and, as indicated, will add rigidityto the chair.

A chair produced in accordance with this invention can be readilyasembled since there are few parts and these can be replaced readily, ifnecessary, for purposes of repair.

I claim:

1. A chair having a seat frame, legs each di-' rectly connected to twoadjacent sides of the frame and within the frame at the corners thereof,the rear legs extending upwardly through the frame to provide a supportfor a chair back, said rear legs at two sides thereof having undercutportions providing recesses to receive the adjacent sides of the seatframe at the corners, the front legs having undercut portions providingrecesses to receive the sides of the seat frame at the front thereof,brace members extending across each of the corners of the seat frame andhaving one side thereof engaging a leg to impart rigidity to the chair,at least one corner block united to one side of each leg andthe'adjacent side of the seat frame, a chair back secured to 5 theextensions of said rear legs, and a seat positioned on said frame andsupported by said frame. by said legs, and by said braces, said seat cutaway to permit the Ices to pass upwardly having the back cornersextensions of the rear therethrough.

2. A chair according to claim 1 wherein the adjacent ends of said seatframe meet in mitered joints to form the corners and are connected byembedded metal strips extending across the corner joints.
